WILLIAM OLIVER, OF LONDON, ENGLAND, ASSIGNOR TO MESSIEURS DANIEL JUDSON & SON, (LTMITED,) OF SAME PLACE.

COIN-OPERATED INDUCTION-COIL.

SPECIFICATION forming part of Letters Patent No. 372,168, dated October 25, 1887.

Application filed January 22, 1887. Serial No. 225,230. (No model) Patented in England July 20, 1886, No. 9,939.

To aZZ whom, it may concern:

Be it known that I, WILLIAM OLIVER, a

' subject of the Queen of Great Britain, residing at Albert House, Canonbury, London, England, have invented an Improved Coin-Operated Induction-Coil, (for which I have obtained a patent in Great Britain, No. 9,939, bearing date July 20, 1886,) of which thefollowing is a specification.

My invention relates to a machine for automatically indicating on a dial, or registering by other means-such as printing or marking on a card or other substance the relative strength of an electric, a faradic, or galvanic current which is being administered, and at the same time exhibiting an advertisement or not, the whole to be rendered workable by the dropping in of a coin or coins.

The invention consists in the construction and combination of parts, which will be hereinafter fully described and claimed.

In the accompanying drawings, Figure 1 is a horizontal sectional View of one form of apparatus in which the degree of strength of the electric current is indicated on a dial. Figs. 2 and 3 are detailviews of the sliding bar and coin-actuated locking and releasing device. Fig. 4 is a vertical sectional view of another form of apparatus which has means for printing on cards and is combined with advertising devices. Fig. 5 is a front view of the casing, showing handle-electrodes, indicating-dial, and advertising-apron. Figs. 6 and 7 are side and top views of the card marking and ejecting device. Fig. 8 is a perspective View of the advertising devices. Fig. 9 is a detail View of the coin-chute and slide-bar. Fig. 10 is a View of a numbered ticket after it has been marked to indicate forty-five degrees of current strength.

Referring to Fig. 1, the reference-numeral 2 designates a casing or box which incloses a faradic or other desired type of inductorium, g. In the present instance the secondary coil of said inductorium is made in sections, each containing an increasing number of strands or These wires or sections are connected in series, and each section is connected with a contact-plate, 2, made of metallic and insulating sections. A horizontal bar, a, is free to slide within the casing between suitable rollers, d, and to the front of this bar is connected a handle, I), the stem of which can slide through the front wall of the casing 2. A contact-finger, it, carried by the bara, moves over the contact-plate 'i, and is successively brought in contact with themetallicportions thereof. A spring, 0, connected with the bar a and with a stud on the casing 2, serves to return the same to the position seen in Fig. 1 as soon as the pressure which has moved the bar backward is removed.

A voltaic battery of any desired number of cells,-k, is arranged within the casing 2, and has its negative and positive terminal. wires Z m connected, respectively, with circuit-closing plates or and one terminal of the primary coil of theinductorinm and with the other terminal of said primary coil. As has already been stated, the different sections of the secondary coil of the induotorium are all connected with the contact-plate, and the other terminal wire,

4;, of said united coils is carried to a fixed handle, 12, extending from the front of the casing. The bar a is of suitable length to break the primary circuit when it is in its normal posi-.

tion. Whcn, however, it is pushedinward, a metal rear portion thereof insulated from the main portion moves over or touches both the contact-plates m, hence closing the primary circuit. At the same time secondary currents are induced in the inductorium and are con- Veyed by the bar a and wire 1) to the handles b b, and they are applied to the person having hold of said handles.

An arm, 6, projecting from the bar a, has attached a cord, n, which passes over guidepulleys q, and is connected with a pulley, p, on the arbor of a pointer, 1", which passes over the index-scale r.

It will be seen that by pushing the bar a in an inward direction the pointer is rotated to move from zero to any number within the range of its movement.

The bar a is normally held in a locked posi" tion by means of the devices seen in Figs. 2 and 3. These consist of the hooked levercatch 8, which is pivoted to some suitable portion or bracket of the casing 2, and is adapted to co-operate with the pins u and u, arranged one in advance of the other on the bar a.

When the bar a is in its normal position, the

clutch-1ever assumes the position seen in Fig. 2 and covers the lower mouth of a vertical tube or chute, it. By dropping into said chute a coin, T of a suflicient weight to tip the lever s, the hook portion thereof is released from the pin u, and then the falling of the weight into a suitable receptacle beneath and the movement of the bar a will bring it into the position shown in Fig. 3. The restoration of the bar a to its normal position by the action of the spring will again cause the lever 8 to lock the bar a until a new coin is inserted, when said bar is again free to be moved inward.

It will be seen that the degree of movement of the bar a determines the number of secondary coils of the inductorium which are thrown into circuit, and hence the degree or intensity of the current administered can be read on the dial 1;.

It is obvious that when the bar a is moved inward to its full extent all the coils are in circuit and the current is then of maximum strength.

Figs. 4 and 5 are sectional and front elevations ol'an apparatus in which the push-bar a is moved by turning the handle I), the spindle w of which carries a bar, y.connected by a chain, 2, with the movable bar a.

In the construction shown the variation of the intensity of the induced current is obtained by the mode of regulation shown in Fig. 1 and by moving the coref of the inductioncoil by connecting said core with the bar a by apendent arm, 0. It will thus be seen that when the handle I) on the spindle wis turned the bar is moved, and, according to the degree of insertion of the core f into the coil 9, the current is intensified. The secondary current is transmitted to the electrode-handles b and b, in the construction shown in Fig. 4, by the wire 2; to the fixed handle I), and the contacts iand h and metal bar a, arm y, and spindle w to the movable handle Z), mounted on said spindle. Circuitbreakcr 5 is combined with the primary circuit and induction coil in the arrangement seen in Fig. 4.

A is an endless band for carrying advertisements. It passes round rollers B B and is actuated by an inclined plane, 0, on the movable bar a. The movable bar is provided with an inking appliance and means for expelling cards D from the box IE. (Shown separately at Figs. 6 and 7, which are side and top views, respectively.)

F is the printing-roller, the arm G of which is supported by the block H and carries the arm J of the ink cylinder K, both being pressed upward bythe springs L and M, so that the printing-roller F projects through a slot in the top plate,N,(which plate is screwed to the movable bar a,) for'the purpose of marking the card which rests on theledges P,forming the bottom of the card-box E. (See Fi 4.) The card-expelling spring Q is fixed by two screws to the plate N, and is bent upward or has a detent or claw, R, at its free end. When the appliance is not in operation, the cards in the box are kept down on the bottom P thereof by a weight, S, and press down the claw R on the spring Q. When the bar a is moved,it carries the printing-roller F from beneath the ledge P of the card-box and draws it along the bottom card, thereby printing an inscription thereon. On releasing the bar a the printing-roller F moves back over the same line, and the claw R- takes against the card and pushes it forward partly through the orifice '1, so thatit can be pulled out, the printingroller returning under the ledge P, so as not to ink the card.

Fig.8 is a perspective view of the advertis-' ing arrangement. The endless band A has secured to it advertisementshcets U U,whieh can fall one by one as they are released from the pressureroller V, suspended from the top of the box or frame. The endless band A is retated in the following manner: On the bar a being moved the inclined plane 0 forces up the roller on the bcll-crank lever W, and with it the push-pawl X, which, taking against the pins Y on the roller B, causes the endless band to move sufficiently to let one advertisementsheet fall. The pawl Z prevents the band from moving in the wrong direction.

Fig. 9 is a perspective view of the moneytube t, said tube being slotted, as shown, so that although a coin of the proper value can slide down to rest upon the catch 8, a smaller coin will fall through the slot into the box heneath without operating the mechanism.

I claim as my invention- 1. The combination of a box or casing, a battery, a sliding bar carrying a contact-piece, an induction-coil and contact-pieces connected to wires of different electrical resistances wound upon said coil, electrical connections between said battery and coil, a catch for locking the sliding bar, means for releasing said catch by placing a proper coin in the apparatus, two operating-handles, one of which is connected with the sliding bar, electrical connections between said handles and the induc- 'tion-coil, an index, and connections between said index and the sliding bar, substantially as herein set forth.
